Abstract

A method for controlling a combustion operation of a cooking appliance, the cooking appliance including a main body having a cooking chamber formed therein, a first heating assembly including a first heater provided inside of the cooking chamber and configured to generate an air circulation flow to circulate heated air inside of the cooking chamber, and a second heating assembly including a second heater provided outside of the cooking chamber and configured to generate heat under the cooking chamber, the method comprising: a simultaneous operation of simultaneously operating the first heating assembly and the second heating assembly; and a partial operation of operating only one heating assembly of the first heating assembly and the second heating assembly.

First claim

What is claimed is:

1. A method for controlling a combustion operation of a cooking appliance, the cooking appliance including a main body having a cooking chamber formed therein, a first heating assembly including a first heater provided inside of the cooking chamber and configured to generate an air circulation flow to circulate heated air inside of the cooking chamber, a second heating assembly including a second heater provided outside of the cooking chamber and configured to generate heat under the cooking chamber, a flow path connection member configured to form a path through which the heat generated in the second heating assembly is introduced into the cooking chamber through a side portion of the cooking chamber, and a first discharge port, which allows the inside of the cooking chamber to communicate with the outside of the cooking chamber, formed in the main body, wherein the path formed by the flow path connection member connects an inside of the second heating assembly and the first discharge port, wherein the main body further includes a lower space formed under the main body and separated from the cooking chamber, and a side space formed at a side of the main body and separated from the cooking chamber, wherein the first discharge port passes through a side surface of the cooking chamber and allows the cooking chamber to communicate with the side space, and wherein the flow path connection member connects the inside of the second heating assembly and the first discharge port, and the path formed in the flow path connection member is separated from the lower space and the side space, the method comprising:
a simultaneous operation of simultaneously operating the first heating assembly and the second heating assembly; and
a partial operation of operating only one heating assembly of the first heating assembly and the second heating assembly.

2. The method of claim 1 , wherein the simultaneous operation and the partial operation are alternately performed.

3. The method of claim 1 , wherein in the partial operation, the first heating assembly and the second heating assembly are alternately operated.

4. The method of claim 1 , wherein the partial operation proceeds after the simultaneous operation has proceeded for a predetermined period of time, and wherein a point in time when the simultaneous operation switches to the partial operation depends on a temperature inside of the cooking chamber.

5. The method of claim 1 , wherein when the operation of the second heating assembly is performed, air heated by the heat generated in the second heating assembly is discharged into the cooking chamber through the flow path connection member.

6. The method of claim 1 , wherein in the partial operation, the operation of the first heating assembly is stopped, and only the operation of the second heating assembly is performed.

7. A method for controlling a combustion operation of a cooking appliance, the cooking appliance including a main body having a cooking chamber formed therein, a first heating assembly including a first heater provided inside of the cooking chamber and configured to generate an air circulation flow to circulate heated air inside of the cooking chamber, a second heating assembly including a second heater provided outside of the cooking chamber and configured to generate heat under the cooking chamber, a flow path connection member configured to form a path through which the heat generated in the second heating assembly is introduced into the cooking chamber through a side portion of the cooking chamber, and a first discharge port, which allows the inside of the cooking chamber to communicate with the outside of the cooking chamber, formed in the main body, wherein the path formed by the flow path connection member connects an inside of the second heating assembly and the first discharge port, wherein the main body further includes a lower space formed under the main body and separated from the cooking chamber, and a side space formed at a side of the main body and separated from the cooking chamber, wherein the first discharge port passes through a side surface of the cooking chamber and allows the cooking chamber to communicate with the side space, and wherein the flow path connection member connects the inside of the second heating assembly and the first discharge port, and the path formed in the flow path connection member is separated from the lower space and the side space, the method comprising:
a simultaneous operation of simultaneously operating the first heating assembly and the second heating assembly; and
a partial operation of operating only one heating assembly of the first heating assembly and the second heating assembly, wherein the simultaneous operation and the partial operation are alternately performed, and wherein in the partial operation, the first heating assembly and the second heating assembly are alternately operated.

8. The method of claim 7 , wherein the partial operation proceeds after the simultaneous operation has proceeded for a predetermined period of time, and wherein a point in time when the simultaneous operation switches to the partial operation depends on a temperature inside of the cooking chamber.

9. A method for controlling a combustion operation of a cooking appliance, the cooking appliance including a main body having a cooking chamber formed therein, a first heating assembly including a first heater provided inside of the cooking chamber and configured to generate an air circulation flow to circulate heated air inside of the cooking chamber, a second heating assembly including a second heater provided outside of the cooking chamber and configured to generate heat under the cooking chamber, a flow path through which the heat generated in the second heating assembly is introduced into the cooking chamber through a side portion of the cooking chamber, and a first discharge port, which allows the inside of the cooking chamber to communicate with the outside of the cooking chamber, formed in the main body, wherein the path formed by the flow path connection member connects an inside of the second heating assembly and the first discharge port, wherein the main body further includes a lower space formed under the main body and separated from the cooking chamber, and a side space formed at a side of the main body and separated from the cooking chamber, wherein the first discharge port passes through a side surface of the cooking chamber and allows the cooking chamber to communicate with the side space, and wherein the flow path connection member connects the inside of the second heating assembly and the first discharge port, and the path formed in the flow path connection member is separated from the lower space and the side space, the method comprising:
a simultaneous operation of simultaneously operating the first heating assembly and the second heating assembly; and
a partial operation of operating only one heating assembly of the first heating assembly and the second heating assembly.

10. The method of claim 9 , wherein the simultaneous operation and the partial operation are alternately performed.

11. The method of claim 9 , wherein in the partial operation, the first heating assembly and the second heating assembly are alternately operated.

12. The method of claim 9 , wherein the partial operation proceeds after the simultaneous operation has proceeded for a predetermined period of time, and wherein a point in time when the simultaneous operation switches to the partial operation depends on a temperature inside of the cooking chamber.

13. The method of claim 9 , wherein in the partial operation, the operation of the
